TOP 10 VOCAB WORDS Flashcards
(23 cards)
Relative Flexibility
The body’s tendency to take the path of least resistance
Autogenic Inhibition
States that a prolonged golgi tendon stimulation inhibits muscle spindles of the same muscle
Reciprocal Inhibition
When an agonist receives a signal to contract an inhibitory signal is sent to its antagonist muscle which lengthens
Synergistic Dominance
When a synergist muscle takes over for an agonist muscle that exhibits a decrease in neural drive
Precomtemplation
Not thinking about working out (Stage 1 of change)
Glucogenesis
Creation of new glucose via non carbohydrate substrates, such as protein
Extrinsic Motivation
Reward/Recognition (ex: winning 1st place in a race, cash prize, trophy)
Agonist
Prime mover for a lift i.e Military Press (deltoid; synergist triceps, antagonist last), Bench Press (chest; synergist triceps, antagonist posterior deltoid), Squats (quads, knee / glutes hip; synergist hamstrings, antagonist psoas
Heart Anatomy
SA Node (pacemaker of the heart), pulmonary artery (CO2 AWAY from the heart), Atriums (hold blood), 140/90 hypertension (systolic/diastolic)
PHA= Peripheral Heart Action: Squats to Push-Ups (upper-lower body exercise)
OTP Model Acute Variables
Rest, Reps, Intensity, Tempo
Davis Law
States that soft tissue molds along a line of stress
Altered Reciprocal Inhibition
Overactive agonist muscle decreases neural drive to a functional antagonist muscle
Sliding Filament Theory
Muscle contraction involving action & myosin sliding past one another shortening muscle during concentric muscle action
Intrinsic Motivation
You feel a sense of satisfaction, belonging (ex: a grandma is happy because she can play with her grandkids due to exercising regularly)
ALL or Nothing Principle
Motor units can’t vary amount of force they generate, they either contract maximally or not at all
Length-Tension Relationship
Resting length if a muscle and the tension it can produce at this length, AKA relationship between actin & myosin (myosin is the larger myofilament)
Principle of Specificity
States that the body will adapt to specific demands that are placed on it
Neuromuscular Specificity
Refers to speed of contraction & exercise selection
Mechanical Specificity
Refers to weight & movement placed on the body
Type I vs Type II muscle fibers
Sprinter= 2 (fast twitch) marathon runner= 1 (slow twitch)
Type I= aerobic/fat utilization, Type II= carbs
Bio Energetics
Phosphagen= high intense/explosive with long recovery (when creatine is used)
Glycolysis
Middle (mod intensity)
Oxidation
Low intense/short rest periods
